As a certified reference material (CRM), Cetylpyridinium Chloride Impurity 1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Cetylpyridinium Chloride Impurity 1 (CAS CATO-C4X-27871) is a certified pharmaceutical impurity reference standard with the molecular formula C23H42NClH2O and a molecular weight of 386.06 g/mol.
The molecular framework of Cetylpyridinium Chloride Impurity 1 (C23H42NClH2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
